Specification of Letters Patent.

Applicatiim filed January 19,1906. $erial No. 241,856.

Patented Nov. 28, 1905.

clare the following to be a full, clear, and ex-- act description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to hooks, and more particularly to boat-hooks, and hasfor its object to provide aboat-hook which will be equipped with a retractable point as well as the usual lateral arm, so that the point may be withdrawn into the body of the hook when the latter is used with its lateral arm,

the point being thus prevented from injuring a person or object with which it might otherwise come into engagement.

Other objects and advantages will be apparent from the following description, and it .will be understood thatmodiflcations in the specific construction shown and described may be made and that any suitablematerials may be used without departing from the spirit of the invention. 7

In the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts in both views, Figure 1 is a side elevation of the hook with the point projected. Fig. 2 is a longitudinal section with the point retracted. C

Referring now to the drawings, the present hook comprises a stock 5, havin a polereceiving recess 6 in its upper end and having also the usual laterallyextending hooked arm 7 adjacent to its lower end. The tion 9 of the stock which extends beyond the arm 7 has a passage 8 opening throu h its free end, and this passage extends longitudinally through the stock and communicates with the recess 6. The outer end portion of the passage 8 is reduced, as shown at 10, re-

sulting in a shoulder 1 1. Formed in the face' 'of the stock at the side opposite to the army 7 there is a recess 12,which communicates with the passage 8 adjacent to and above the shoulder' 11, and extending outwardly through.

this recess and projecting beyond the face of the stock there is the stem 13 of a 'lever, 14,

the head 15 of which is pivoted in the larger por-,

portion of the passage 8 and spaced from the shoulder 11. The head 15 of the lever consists of a portion 16 which extends laterally beyond the stem 13 in the direction of'the portion 10 of the passage, and the face 17 of this portion 16, which is the face lying. in-the direction of the free end of the lever, extends at right angles to the stem 13, while the opposite face of the portion 16 is curved, as shown at 18, to present a cam-face. The lever is pivoted at a point at theextremity of the head and eccentricall-y to the curvature of the face 18.

. Slidably engagedin the reduced portion 10 of the passage 8 there is a point 19, including a sharpened pin 20, havin a laterally-extending flange 21 at the on opposite to the 'point, this flange being larger than the portion 10 of the passage and lying within the lar er portion of the passage into which the en of the pin projects. Disposed between the flange 21 and the shoulder 11 there is a helical sprin 22, which is engaged with the pin and whic holds the point yieldably with its sharpened end'within the passage.

The lever 14 is movable upon its pivot to bring either its straight face 17 or its curved face ,18 into engagement with the rearward end of the point, and the arrangement is such that when the straight face is in engagement therewith the point is held with its shar ened end projected beyond the end of t e stock. When the lever is moved to bring its curved face 18 into engagement with the point, the point is moved into the stock by the spring 22, the curved face being of less eccentricity than the straight face.

The use of the invention will be readily un derstood without further description.
